Obligate parasite An obligate parasite, or holoparasite, is a parasitic organism that cannot complete its life-cycle without exploiting a suitable host.If an obligate parasite cannot obtain a host it will fail to reproduce.This is opposed to a facultative parasite, which can act as a parasite but does not rely on its host to continue its life-cycle.f an obligate parasite cannot obtain a host it will fail to reproduce. This is opposed to a facultative parasite, which can act as a parasite but does not rely on its host to continue its life-cycle.

Intestinal Parasites * parasites (PAIR-uh-sites) are organisms such as protozoa (one-celled animals), worms, or insects that must live on or inside a human or other organism to survive. An animal or plant harboring a parasite is called its host. Parasites live at the expense of the host and may cause illness.* gastrointestinal (gas-tro-in-TES-tih-nuhl) means having to do with the organs of the digestive system, the system that processes food.n animal or plant harboring a parasite is called its host.

- A parasite is an organism living on or in another organism and using the other organism for food or energy. Since a parasite is something that infects your body, they can cause infectious disease. Parasites are totally creepy to think about.hey are less common than bacteria and viruses, but they can be just as deadly. The other main types are: fungi and parasites. Fungi are living things found in the Eukarya domain. They can be found all over the place such as in soil, on vegetation, and even on parts of our bodies.

- A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.rotozoa that live in the blood or tissue of humans are transmitted to other humans by an arthropod vector (for example, through the bite of a mosquito or sand fly). Entamoeba histolytica is a protozoan.

ISEE Test Like protozoa, helminths can be either free-living or parasitic in nature. In their adult form, helminths cannot multiply in humans. There are three main groups of helminths (derived from the Greek word for worms) that are human parasites:1  Flatworms (platyhelminths) – these include the trematodes (flukes) and cestodes (tapeworms). 2  Thorny-headed worms (acanthocephalins) – the adult forms of these worms reside in the gastrointestinal tract.here are three main groups of helminths (derived from the Greek word for worms) that are human parasites: 1  Flatworms (platyhelminths) – these include the trematodes (flukes) and cestodes (tapeworms). 2  Thorny-headed worms (acanthocephalins) – the adult forms of these worms reside in the gastrointestinal tract.

Pathogens These bacteria must also infect a host in order to survive, in contrast to other bacteria that are capable of survival outside of a host. Examples of obligate bacterial pathogens include Mycobacterium tuberculosis and Treponema pallidum. Opportunistic pathogens can be transmitted from one host to another without having to cause disease. However, in a host whose immune system is not functioning properly, the bacteria can cause an infection that leads to a disease.

What are the differences between Bacteria, Viruses, Fungi and Parasites? A parasite is an organism that lives on or in a host and gets its food from or at the expense of its host. Parasites can cause disease in humans. Some parasitic diseases are easily treated and some are not. The burden of these diseases often rests on communities in the tropics and subtropics, but parasitic infections also affect people in developed countries. More about parasites ».
